stagnation point flow of thixotropic fluid over a stretching sheet with mass transfer and chemical reaction

The stagnation point flow of thixotropic fluid towards a linear stretching surface is investigated. mass transfer with first order chemical reaction is considered. the resulting partial differential equations are reduced into the ordinary differential equations. dimensionless velocity and concentration fields have been computed. graphical plots are presented to illustrate the details of flow and mass transfer characteristics and their dependence upon the physical parameters. numerical values of surface mass transfer are first computed and then analyzed.
